"I actually skipped the hospital," Lilly explained, during an appearance on The Tonight Show with Jay Leno. "We decided to have the baby at home because we wanted it to be a natural birth, and it turns out that it was 30 hours of natural!"

Lilly recalled how after five hours of pushing, her midwife and birthing assistant stepped in to help speed up the process.

"I was like, 'Really? After five hours of pushing, you have a few suggestions? You couldn't have told me five minutes in?'"

The actress also recalled telling press that she planned to take a break from acting after the birth, until director Peter Jackson asked her to be part of the Hobbit films.

"I was sitting with my newborn baby and Peter Jackson called and said, 'Would you like to be an elf in The Hobbit?' Lilly revealed. "So I'm sort of strapped in, as it turns out, to four movies now."
